- "Let's give ourselves a big thumbs up!"
- — Alpha Pig, after waking up Alisa and Xiaoyu.
Alpha Pig is Pig's transformed self. His rock alphabet toolbox includes an Rock Alphabet Map, Rocky Letter Lasso, Brilliant Rockulars, Meteor Magnifying glass, and a Galactic Flashlight.
Alpha Pig usually uses his skills to build items to help wake Alisa Bosconovitch and/or Ling Xiaoyu. To do this he simply builds his wooden letters and then uses them to build or fix the desired object in question by spelling a word resembling it; alternatively, he can just whack them with a hammer.
During Barney and the Rocko Squad, Alpha Pig, Barney, and the other Super Readers keep track of Xiaoyu's crying.
Zachary Bloch voices Alpha Pig in Barney and the Rocko Squad.
